These cells are the gametes - sperms in males and egg in females. In meiosis, however, you start with a diploid cell that divides twice to produce four haploid cells. Meiosis II is not a reduction division because, although there are fewer copies of the genome in the resulting cells, there is still one set of chromosomes, as there was at the end of meiosis I. The haploid cells produced by meiosis are germ cells, also known as gametes, sex cells or spores in plants and fungi. There are two stages or phases of meiosis: meiosis I and meiosis II. Four genetically different cells. Four of the five answers listed below are characteristics of meiosis. The process in males and females also differ especially in terms of the actual gamete produced. At the end of meiosis-I, two daughter cells are formed having half the number of chromosomes present in diploid cell undergoing meiosis. Cross-over. Finally, in the G 2 phase . The second part of the meiosis, meiosis II, resembles mitosis more than meiosis I. Chromosomal numbers, which have already been reduced to haploid n) by the end of meiosis I, remain unchanged after this division. Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. Meiosis is the type of cell division that createsgametes.Gametes do not undergo cellular division - they are the end result or product of meiosis. Similarities Between Mitosis and Meiosis.
